hello I have a '98 benz c230 and am thinking about purchasing a KOMPRESSOR supercharger for it. Does anyone know any differences between the KOMPRESSOR and non-KOMPRESSOR editiions of the '98 C230? Is the only difference the addition of the supercharger and the letters on the trunk? Do you know if the engine cover looks and different and can you attach a pic? Thanks alot! I greatly appreciate any advice anyone's willing to give.
